Bedrock uniBTC vs Function FBTC: Which fits? (2026)

Bedrock uniBTC and Function FBTC both give users exposure to a Bitcoin-backed token, but their approaches differ. Bedrock routes BTC into Babylon staking, offering a route to Bitcoin staking yield without selling BTC. It lists 18 chains, including Bitcoin, Ethereum, Base and Arbitrum, and has a dashboard for holdings and vault performance. Function describes FBTC as wrapped Bitcoin backed by core contributors Antalpha Prime, Mantle and Galaxy Digital. It lists Bitcoin as its chain and claims 30+ integrations, including vaults on Ethereum and Solana. Function has the larger TVL, at about $666 million versus Bedrock’s roughly $340 million. That indicates greater tracked value, not a guarantee of safety or liquidity. Choose based on the structure and access you need: staking and broad listed chain coverage point toward uniBTC; a wrapped-BTC asset with listed audits points toward FBTC.

Neither project publishes minting or redemption fees in the details here. Bedrock also does not publish fee or yield figures, so you cannot compare a stated net return with FBTC. For uniBTC, budget for gas on the chosen network and any swap or bridge costs when moving the token. Its yield depends on Babylon Bitcoin staking, and any extra vault strategy may have additional terms. Function says vault APYs are estimates shown as ranges, not guaranteed returns. Third-party vaults and lending markets, including Aave and Kamino, set their own terms and costs. Before using either token, check the project’s current documentation and app for applicable charges, and include any third-party costs in your calculations. Do not treat an advertised or estimated yield as a promise of what you will receive.

The risks differ, but neither token is equivalent to holding Bitcoin directly. Bedrock has no audits listed, and its uniBTC model adds Babylon staking risks as well as smart-contract, cross-chain, depeg and liquidity risks. Bedrock mentions Chainlink Proof of Reserve, which offers an on-chain check on backing but does not guarantee redemption. Function lists two audits and provides Proof of Assets and a Risk Disclosure Statement. Its custody details beyond the named contributors are not public, so holders still face custodian and counterparty risk alongside smart-contract and wrapper risk. Audit listings are useful information, not a guarantee against loss. Before using either project, inspect current audit reports, reserve information, custody terms and redemption conditions. Consider the possibility that a token could trade below its intended value or be difficult to redeem.

Bedrock’s listed coverage across 18 chains gives uniBTC more choice of networks, and its dashboard brings holdings and vault performance together. That breadth also means you should check liquidity and bridge or cross-chain risks on the specific network you plan to use; availability across many chains does not ensure equal liquidity everywhere. Function’s chain list includes Bitcoin, while its stated integrations and vaults extend to Ethereum and Solana. Some homepage fields, including TVL, holders, minimum amount and vault cap, may render as blank, zero or NaN, making live site data harder to verify. Both projects have an ease-of-use score of 6.5, so the listed score does not separate them. In practice, compare the actual token availability and redemption route for your intended use, and verify current figures before committing funds.

Choose Bedrock uniBTC if you specifically want a route into Babylon Bitcoin staking and value access across many listed chains. Its Proof of Reserve mention and position dashboard may also suit users who want visibility into backing and holdings, but its fees and yield are not published, and no audits are listed. Choose Function FBTC if you prefer a wrapped-Bitcoin asset, put more weight on its higher TVL and two listed audits, and are prepared to investigate custody arrangements and counterparty risk. Function’s vault APYs are estimates, and some live site fields may be difficult to verify. Neither is the clear choice for every Bitcoin holder: the deciding questions are whether you want a staking route or a wrapper, which network you need, and which risks you are willing to accept.
